[TRNSYS-users] Ventilated Facade

[Technical Support]

Davide,
 How wide is the airgap behind the wood? We wrote some models a few months
ago to simulate a similar facade that had a ceramic tile outer skin and
about a 3cm air gap behind, then concrete, then drywall. We used CONTAM
to determine the flow of air that was induced in the air gap but you
could equally well use COMIS or TRNFlow. The model interfaces with Type56
by calculating a boundary temperature between the ventilated part of the
wall and a part of the wall that is specified in TRNBuild and modeled by
Type56.
Kind regards,
 David
